To Set Forced Mode and Disable Autonegotiation
1. Use the
ndd
utility to select the
qfe
instance that you want to set.
See “Identifying Device Instances” on page 65 for more information.
2. Select one of the four operational mode parameters (
adv_100fdx_cap
,
adv_100hdx_cap
,
adv_10fdx_cap
, or
adv_10hdx_cap
), and use the
ndd
utility
to set its value to 1.
For example, to set the 10 Mbps, half-duplex mode, you would set the
adv_10hdx_cap
parameter to
1
.
If you set more than one of the operational mode parameters to 1, the driver will
select the mode that is highest in the priority order (see “Operational Mode
Parameters” on page 62 for more information).
3. Use the
ndd
utility to disable autonegotiation by setting the
adv_autoneg_cap
parameter to 0.
